Provision

One property carries everything rich an element publishes to the document, so Quark and app JS have a single place to read it.

Declaring a provision

All public, rich data an element exposes to the document goes through one property: provision. Declare it as provision: Object (or a typed constructor), set it from an effect, and tag it @provision in JSDoc.

Neutron({
  tag: "provider-ping",
  props: { provision: Object },
})
  .onConnected(() => ({ provision: { at: Date.now() } }))
  .define();

Reading it

Every set emits neutron-provision for app JS. Quark reads it on the element itself with prop("provision") and re-runs when it is assigned — assign a new object rather than mutating the old one.

provider-ping {
  $ping: prop("provision");
  [bind-at] { content: $ping.at; }
}

Ordering

Within one effect, provision is always applied last, so listeners of neutron-provision see every other prop already settled.
